J Burn Care Res. 2017 Jan/Feb;38(1):e36-e41 Authors: Wong BM, Keilman J, Zuccaro J, Kelly C, Maynes JT, Fish JS Abstract The use of ablative fractional carbon dioxide laser therapy and pulsed dye laser therapy has led to significant improvements in the rehabilitation of hypertrophic burn scars. However, laser procedures are associated with appreciable pain among pediatric patients. Clinical consensus suggests using general anesthesia for pediatric laser procedures; however, guidelines for perioperative care are lacking. The objective of this quality improvement study is to determine whether a difference exists in postoperative pain outcomes in pediatric patients who receive intraoperative opioid regimens compared with patients who receive opioid-sparing regimens for laser therapy of hypertrophic burn scars. A retrospective review of patients who received laser therapy at a pediatric burn center from April 2014 to May 2015 was performed. Overall, 88 of the 92 procedures reviewed were included. A statistically significant difference was not found between the likelihood of postoperative pain when intraoperative opioid regimens (n = 63) were given compared with opioid-sparing regimens (n = 25) X (1, n = 88) = 2.870, P = .0902. There was also no difference between short-acting (n = 48), long-acting (n = 9), or combination (n = 6) intraoperative opioids compared with opioid-sparing regimens (n = 25) in the likelihood of postoperative pain. Despite the small sample size, the low number of postoperative pain cases is encouraging. Ultimately, these data provide a foundation for developing anesthetic guidelines for pediatric laser procedures. Specifically, clinicians should consider the potential to deliver adequate perioperative care via an opioid-sparing regimen ± adjuvant. PMID: 27532615 [PubMed - indexed for MEDLINE]

Noninvasive Techniques for the Determination of Burn Severity in Real Time.

J Burn Care Res. 2017 Jan/Feb;38(1):e180-e191 Authors: Burmeister DM, Cerna C, Becerra SC, Sloan M, Wilmink G, Christy RJ Abstract Visual diagnosis of second-degree burns has proven inadequate for determining the appropriate treatment regimen. Although multiple noninvasive imaging techniques have shown promise for providing information about burn wound severity, the ideal technology to aid burn wound excision would provide real-time readouts. Herein, the authors examine a high-resolution infrared (IR) camera (thermography) and a multiprobe adapter system (MPAS-6; transepidermal evaporative water loss, colorimetry) to assess their usefulness in predicting burn severity. Contact burn wounds of increasing severity were created in a porcine model. Wounds were assessed for 4 days with an IR camera and MPAS-6. In addition, each day, the burn wounds were biopsied for histological analysis to determine burn depth for correlation with noninvasive measures. Surface temperatures decreased with increasing burn severity, which was associated with increasing transepidermal evaporative water loss. Melanin content correlated with the depth of collagen coagulation and was bimodal, with superficial and full-thickness burns having higher values than deep partial thickness wounds. Erythema content was highest in superficial burns and negatively correlated with necrosis (high-mobility group box protein 1 expression). Importantly, surface temperature taken on every single day after injury was predictive of all histologically determined measurements of burn depth (ie, collagen coagulation, apoptosis, necrosis, vascular occlusion). The results indicate that IR imaging and skin quality probes can be used to support the diagnosis of burn severity. Most importantly, IR measurements gave insight into both the zone of coagulation and the zone of stasis on every postburn day studied. PMID: 27355653 [PubMed - indexed for MEDLINE]
